There are many new players asking on Facebook about the awakening quests and also I've seen players asking here. So I am making this topic.
What is the awakening?
Once selected Heroes have reached Orange fusion and level 90, you will have an option to awaken the hero through a series of quests. To check a step by step about the awakening keep reading to see Arachna's Awakening Quest:
See the glowing question mark in the top left of Arachna’s equipment grid? That means an awakening quest is available. Click on it to begin.
The first Awakening Quest for all heroes is to craft their signature item. Each hero has a signature item which is unique to them and used to complete their awakening. In Arachna’s case, the item is “Silk Veil”. You will have to collect several ordinary items plus another specialized item, “Silk Strand” which is also unique to Arachna. The fragments of the specialized item can be found in a single chapter 14 heroic stage. Once you have the necessary components, you may craft and equip the signature item.
The details of the next awakening quest are different for every hero. For Arachna, the next challenge is to complete “Ride of the Valkyries” in the Dojo 10 times on the highest difficulty level (Extreme). Once this is done she may proceed to her third and final awakening quest.
The last quest is usually the most challenging. These quests involve finishing a certain heroic stage while meeting some additional requirement. For Arachna, she must finish “Ch. 14 – Empty Handed” on Heroic while dealing at least 150,000 damage to enemies.
Once all three quests are completed, your Hero will be awakened. You’ll see a new card and skin for your Hero, and you’ll also unlock a 5th ability, increasing their overall rating! Having a 5th ability can make a huge difference for the effectiveness of a hero.
The awakening quests will challenge you and may take some time to complete, but when you succeed your heroes will be taken to a whole new level!
